What were you expecting!? lol. It makes the air a bit cooler. I put mine on because I was getting heat issues at <210 bhp. I bought the Forge, took it back to Rtec and got 236 bhp. Really isnt worth the coin for that little power. Some say it is but their tryin to justify their 'investment' I might be going back to the old map and OEM intercooler so feel free to make an offer for mine........... Id only bother with one if you go for a big turbo but then the pipes would be wrong.........
